Carefully made specimens of the soft tissues of many plants have shown
a similar protoplasmic continuity, where it had previously been
unsuspected. Some investigators are now inclined to the opinion that
protoplasmic continuity may be of universal occurrence in plants.

ELECTRIC LAUNCHES.
[Footnote: A recent lecture before the Society of ATM, London.]
By A. RECKENZAUN.
It is not my intention to treat this subject from a shipwright's point
of view. The title of this paper is supposed to indicate a mode of
propelling boats by means of electrical energy, and it is to this motive
power that I shall have the honor of drawing your attention.
The primary object of a launch, in the modern sense of the word, lies
in the conveyance of passengers on rivers and lakes, less than for the
transport of heavy goods; therefore, it may not be out of place to
consider the conveniences arising from the employment of a motive power
which promises to become valuable as time and experience advance.
